Methyl 3,4-O-dibenzoyl-2-O-benzyl-1-thio-β-L-fucopyranoside

The title compound, C28H28O6S, is a protected fucose donor, synthesized as part of our investigations into the preparation of complex oligosaccharides. The benzoyl groups are equatorial and axial, while the thio­ether and ether groups are equatorial. The carboxyl­ate O atoms form a number of intra- and inter­molecular C—H⋯O inter­actions.
